Need a bit more information, such as what its behavior is when it doesn't boot (i.e. does it come up with an error message or blue screen of death?). What OS are you running? Is the hard drive making any new or suscipious noises? Please post EVERYTHING you can think of.
There is no blue screen of death no error on a black screen nothing.It doesnt boot at all.I swiched the a/c adapter and the battery.I was running windows xp professional.The hard drive is not making any noise at all.After about 50 times of trying to power on it does power on.It loads till about the windows screen then laptop cuts out and is unresponsive.
I am also having this problem with my Dell Vostro 1000. I turned it on and at first a million different colored lines with across the screen. I turned it off and tried again and then a blank blue screen came up. Third try, black screen. No other noises but a flashing yellow light with an "a" inside on top of keyboard. Operating on Vista. What should I do? firstname.lastname@example.org
